Consider the polar equation r= a cos(8) + b sin(8). (a) Express the equation in rectangular coordinates, and use this to show that the graph of the equation is a circle. What are the center and radius? r = a cos(8) + b sin(6) 2 = ar cos(6) + x2 + y2 = ax + by - ax + - by - 0 x2 - ax +? + y2 - by +62 = 2 + ( + (v - )' - ? + 63) Thus, in rectangular coordinates the center is (x, y) = and the radius is
